How to deal with rust spots on stainless steel
1. In chemical method, acid cleaning paste or spray is used to assist the rusted parts to passivate again and form chromium oxide film to restore their corrosion resistance. After acid cleaning, in order to remove all pollutants and acid residues, it is very important to properly rinse with clean water. After all processing, use polishing equipment to re polish and seal with polishing wax. For areas with slight rust spots, a 1:1 mixture of gasoline and engine oil can be used to wipe off the rust spots with a clean cloth.
2. Mechanical methods include sandblasting cleaning, glass or ceramic particle blasting cleaning, annihilation, brushing, and polishing. It is possible to use mechanical methods to wipe away contamination caused by previously removed materials, polishing materials, or buried materials. All kinds of pollution, especially foreign iron particles, can become sources of corrosion, especially in humid environments. Therefore, it is best to perform formal cleaning on mechanical cleaning surfaces under dry conditions. The use of mechanical methods can only clean its surface and cannot change the corrosion resistance of the material itself. Therefore, it is recommended to re polish with polishing equipment after mechanical cleaning and seal with polishing wax.
